Several events and personal experiences have converged to make me reflect again on American racism’s historical travesties and current oppressions.

Recently I visited the National Museum of African American History and Culture in Washington, DC. It’s the only national museum devoted to documenting African American life, history, and culture and it’s a powerful experience. “Nearly 40,000 objects have been displayed to help all Americans see how their stories, their histories, and their cultures are shaped by a people’s journey and a nation’s story,” the museum’s website says.

Those objects include original documents, artifacts, and memorabilia that bring to life the painful history of African Americans. There are original books by slave poet Phyllis Wheatley and orator Frederick Douglass. There are slave auction documents and drawings of slave ships that reveal how thousands of human beings were forced to lie next to each other like sausages for weeks. There is a shawl given to Harriet Tubman by Queen Victoria, and an actual slave cabin. The history section alone could take days to visit. It would take another day to see the collections in the culture section of this moving museum.

Just after I visited the museum, the National Memorial for Peace and Justice opened in Montgomery, Alabama. The memorial honors 4,400 black people killed by lynching and other racial violence between 1877 and 1950. The memorial is “the country’s first dedicated to the legacy of enslaved black people, people terrorized by lynching, African Americans humiliated by racial segregation and Jim Crow, and people of color burdened with contemporary presumptions of guilt and police violence,” its website points out. You can’t look upon the design of the memorial grounds and the iconic sculptures it exhibits with a dry eye.

Located nearby is the new Legacy Museum: From Enslavement to Mass Incarceration, occupying the site of a former slave pen where auctions were held. An “unflinching reminder of America's racist legacy, the museum details the history of the slave trade and follows through to current-day problems associated with mass incarceration.” The connection it makes clear between slavery, lynching, civil rights, and mass incarceration is vital to understand.

That connection heightened my own awareness of the continuum of racism manifested in today’s police brutality and flawed criminal justice system. It made me think of our overcrowded, for-profit prisons, and of the black youth and men who fill them, many innocent of the crimes they are alleged to have committed, or languishing behind bars because of minor infractions.

According to www.diversityinc.com, last year police killed over 1,000 people, with officers charged with a crime in just one percent of cases. Of those killed, 27 percent were black, despite being 13 percent of the population. In the majority of incidents, officers were responding to non-violent offenses, or no crime had been reported. Eighty-seven people killed were stopped for traffic violations.

One thinks of Eric Garner, Tamir Rice, Michael Brown, and Philandro Castro, among so many others. Or of Glen Ford, one of many black men wrongfully incarcerated for a crime they didn’t commit, who died in 2015 shortly after being released from death row after 30 years.

Not every black person harassed or abused by police ends up in jail. But the indignities many suffer speak volumes about brutality, terror, and criminal injustice. Just recently a mentally disturbed young black man was tased to death in his shower by police when a neighbor reported he’d been acting strangely. (Stories like these go largely unreported.) A recent video went viral when a young black woman in the Los Angeles subway was accosted by police. Bethany Nava was resting her foot on the edge of a seat when an LAPD officer confronted her and then dragged her off the train, handcuffed her, and arrested her for allegedly refusing to remove her foot. Another woman of color, Selina Lechuga, objected to the officer’s handling of Nava. Both women were taken into custody and Lechuga was charged with committing battery against an officer, despite video evidence to the contrary.

Nor does every instance of humiliation or oversight that black people suffer involve the police or the courts. Take, for example, the fact that while touting his friendship with Kanye West, the president saw no reason to honor James Shaw, Jr., the young black man who tackled the Waffle House killer, saving God knows how many people, and then fundraised for victims’ families.

I close with another recent experience. Invited to read from my memoir to a group of students, I chose a piece about an event that occurred when I was young in small town 1950s America, when lunch counters were segregated and the occasional lynching still occurred. The incident resided in racism and having been to the museum in Washington, it seemed a good time to share it. I couldn’t get through it without weeping, because I was reminded that nothing much has changed since those days.

Lonnie Bunch, founding director of the DC museum said, “The African American experience is the lens through which we understand what it is to be an American.” For better or worse, that seems truer today than ever.
